Title: Wood impregnating agent for glazing and internal staining - contains water glazing pigment, film former, biocide, glycol and evaporation regulator
Inventor: BOLLINI TULLIO
IPC: B27K3/50
Filed: 1990-06-27
Abstract: An impregnating agent for glazing and internal dyeing of wood contains water, at least one glazing pigment, a film-forming polymeric binding agent, at least one biocide which acts as a preservative and two or more at least partially water-miscible aliphatic hydrocarbon-free solvents of which one is a glycol and the other regulates evapn. USE/ADVANTAGE - The use of the impregnating agent obviates the need for a special preservative pre-treatment prior to glazing. The agent impregnates the wood more easily and the staining is simpler and easier to achieve than previously. The wood can be permanently and effectively impregnated by only 2 applications of the agents to the surface which renders the wood resistant to external influences and protects it from sun, UV rays and the cold. The resulting appearance of the wood is good. The agent dries at a rate that is neither too fast (which would give a skin or an uneven raw surface) not too slow (which would result in too long a wait between applications).

Title: Insulating glass pane sealing esp. for vehicles - using smoothing roller with translatory movement which also removes surplus adhesive while still soft
Inventor: DIETL UDO DIPL ING
IPC: B60J10/00
Filed: 1990-10-23
Abstract: To seal the edges of an insulating glass pane during mounting, surplus adhesive is removed while it is still soft. A smoothing roller is passed along the edge joint, at the surplus adhesive, in a translatory movement where the roller is rotated against the direction of travel to pick up the surplus adhesive on its mantle surface through the effect of its rotary speed and, simultaneously, the applied adhesive is smoothed. The collected surplus adhesive is removed from the roller mantle by a scraper. The adhesive is pref. applied to the edge joint in front of the smoothing roller, synchronised with its translatory movement. The gap between the adhesive application and the roller is selected to ensure that the adhesive is still soft when the roller comes into contact with it. When a smaller glass pane is to be bonded to a larger pane, the smoothing roller is moved with a translatory motion along the edge of the smaller glass pane. After the adhesive has hardened, the joint is treated by brushing. ADVANTAGE - The technique gives a high-speed sealing and mounting action to the glass panes, without requiring further finishing.

The fifth piston stage is arranged outside the piston cylinder, and consists of two parallel running plates (52) which serve as a guide for a driver component (56) via which the engine can be started. USE - Axial piston engine with a staged piston.
Patent DE-4041205-A1 (DE)
Title: Hot rolling of strip from thin cast sections
Inventor: FASTERT HERBERT
IPC: B21B1/46
Filed: 1990-12-21
Abstract: In a process for rolling out strip from continuous cast bars, several continuous castings are produced in parallel prodn. lines, and sepd. into individual sections. After homogenising in a compensating oven and raising the rolling temp. the sections are transferred to a rolling line. More efficient balancing of casting and rolling capacity is achieved through the use of a swivelling oven in both casting lines and the rolling line. By alternately moving each oven at an angle to the casting lines the metal sections are transferred from each line directly into the single rolling line. The plant has several casting lines each with a swivelling oven. Ovens in adjacent lines are offset by one oven length. On the outer lines the pivot pt. of the ovens is at the rear end and on the central line is at the front.
